The design of centrihgal pump involves a large number of empirical data derived from experimental evaluation of pumps. For any small change in input details, it requires a complete rework of design procedure. Even after following this detailed, time consuming procedure, it was very difficult to explain the geometry of the pump elements. This paper discusses the optimisation and computerisation of the design procedure of single stage centrifUga1 pumps. The design procedure was developed using Graphical User Interface software with Visual Basic 5.0 and interfaced with a specially developed AutoLISP program in AutoCAD R13 environment. An algorithm for generating the Cartesian co-ordinates of the designed pump elements was evolved and incorporated in the program, which are used to show the geometrical shapes of the pump elements and also used as an input data for the Auto LISP program for generating three-dimensional views of the pump components. The options and utilities made available through a single program enables the user to design, view, redesign and optimize the pump geometry till it reaches a satisfactory value. The developed software is user-friendly and can be used as a design tool to configure an optimum pump geometry for a given duty like discharge and head.
